MY DAUGHTER (AGE 19) WAS DRIVING TO A SKATING LESSON WHEN THE PICKUP TRUCK "VEERED TO LEFT" AND SPUN OUT OF CONTROL. IT CLIMBED A GUARDRAIL, WENT UP OVER THE GUARDRAIL, AND ROLLED DOWN AN EMBANKMENT. PIECES OF THE LEFT FRONT TIRE WERE ON THE HIGHWAY AND THE REMAINDER OF THE TIRE WAS SHREDDED. ALL FOUR TIRES WERE OF THE SAME MAKE AND MODEL. I SUSPECTED A BLOW OUT BUT HAD NO WAY OF PROVING IT.( DOT NUMBER: )
